How to fix this subtitle issue on VLC?

[tiulauleejung]

Hello,
This video is a korean drama series in .vob format. This is a dvd ripped video with those subs.
It works on TV but subtitle is sometimes missing or don't work.
I tried playing it on my laptop, and this is how it looks.
Please help me.
I've tried Media Player Classic, but it doesn't show the subs even though it's enable.

Try open the dvd folder(vob, ifo, bup files) in vlc instead of playing vob files.

Or have you deleted the ifo files?

I tried what you said but no change in how the subs was placed.

and I don't think I have the ifo file, I haven't deleted anything too.
